THE MI9535-5XX RECEIVER / CHARGER CRADLE 
The scanner should be fully charged prior to being placed into service. Metrologic 
recommends that Bluetooth communication between the scanner and the cradle 
be established first before charging.  
To charge the scanner, place the unit into the cradle. The amber LED on the 
scanner will begin to flash indicating the charging process has begun.  
For first time installations, leave the scanner in the cradle for a full 3 hours.  
Please note that the amber LED on the scanner will stop flashing after 2.5 hours 
but it is recommended that the scanner be left in the cradle for an additional 30 
minutes to complete the initial 3 hour charge.  
Once the initial 3 hour charge is complete, the battery will only require 2.5 hours 
to come to a full charge when the unit gives a low power warning.  A steady 
amber LED on the scanner will indicate the completion of a full charge.

recharged.
